14 Dive Computers Perfect for 2022
A Garmin dive computer is ready to be used on a dive boat.
How We Test Computers
ScubaLab computer testing is designed to evaluate two aspects of performance: how the computer’s decompression algorithm compares to others, how easily and effectively the computer interfaces with a potential new user in terms of intuitive operation, clarity of data and ease of reading.
To gauge algorithm performance, we conduct a series of four test dives, designed to simulate a full day of diving, at the University of Southern California Hyperbaric Chamber, recording no-deco times at multiple stages during each dive. We use the data to gauge their performance as liberal, conservative or average among the test group.
The divers score computers in nine categories, including intuitive operation, ease of reading underwater and at the surface, ease of navigating menus, and effectiveness of other features such as digital compass and alternate screen data. Divers also rate the effectiveness of a computer’s controls as well as its overall ergonomics.
Simulated dives are conducted in a small pressure chamber to evaluate each computer’s performance in situations not suitable for human test dives, such as warning, alarms and instructions displayed during rapid ascents or missed decompression.
